Types

type Mipmap

type Mipmap struct {
	// contains filtered or unexported fields
}

Mipmap is a set of buffered.Image sorted by the order of mipmap level. The level 0 image is a regular image and higher-level images are used for mipmap.

func New

func New(width, height int, imageType atlas.ImageType) *Mipmap

func (*Mipmap) At

func (m *Mipmap) At(graphicsDriver graphicsdriver.Graphics, x, y int) (r, g, b, a byte, err error)

func (*Mipmap) DrawTriangles

func (m *Mipmap) DrawTriangles(srcs [graphics.ShaderImageNum]*Mipmap, vertices []float32, indices []uint16, colorm affine.ColorM, mode graphicsdriver.CompositeMode, filter graphicsdriver.Filter, address graphicsdriver.Address, dstRegion, srcRegion graphicsdriver.Region, subimageOffsets [graphics.ShaderImageNum - 1][2]float32, shader *Shader, uniforms [][]float32, evenOdd bool, canSkipMipmap bool)

func (*Mipmap) DumpScreenshot

func (m *Mipmap) DumpScreenshot(graphicsDriver graphicsdriver.Graphics, name string, blackbg bool) error

func (*Mipmap) MarkDisposed

func (m *Mipmap) MarkDisposed()

func (*Mipmap) ReplacePixels

func (m *Mipmap) ReplacePixels(pix []byte, x, y, width, height int)

type Shader

type Shader struct {
	// contains filtered or unexported fields
}

func NewShader

func NewShader(ir *shaderir.Program) *Shader

func (*Shader) MarkDisposed

func (s *Shader) MarkDisposed()
